Well, not really evil, unless you’re trying to get other things done.
Whatever you do, do NOT use StumbleUpon.
It sounds so fun: you tell them which topics are interesting to you, and they feed you random sites in that topic.
It is fun — I’ve come across some amazing things recently.
However, I’ve also been all too weak about stopping all the stumbling when I should be doing something else.
Hmmm…Scribbler recently mentioned to me that doing NaBloPoMo is like an anthroposophical will exercise (do something at the same time every day without any external motivation, to build up your will forces). Perhaps I spent all my currently available will forces in November, and will now spend December drooling and slack-jawed in front of my computer.
Let’s hope not.
